Error: jsonrpc2: connection is closed
Opening an .ino file and then doing some edits. Specifically typing:
const char* string = "foo%test";
eventually results in:
jsonrpc2: connection is closed
after which nothing works anymore.

The underlying clangd process crashes. I do not yet know why. I've debugged into the LS and I can confirm this notification is failing, for instance:
https://github.com/bcmi-labs/arduino-language-server/blob/209f1719f13b9343cb9ef074ad39fc1e1bf9fedc/handler/handler.go#L125
See the screencast as "proof":
I can see the following in the inols-clangd-err.log log file:

Can this error cause the clangd crash, @spoenemann? The file /Users/akos.kitta/Library/Arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino5/avr/include/stdlib.h exists by the way.
Update: However, the referenced file #include <stddef.h> from the stdlib.h does not exist, at least in the same include folder:

This is also suspicious;

At the very least, the language server should automatically restart when the connection is closed.
the language server should automatically restart
What do you mean by "should restart", do we have such logic in the LS itself or Arduino Pro IDE, or maybe Theia? Or have you mentioned it as a missing feature?
